Disclosed herein are an apparatus and method for controlling smart wear. The apparatus for controlling smart wear includes a motion capture unit, an error information unit, a motion estimation unit, and an actuation unit. The motion capture unit captures a motion of a user using sensors included in the smart wear. Then error information unit generates user error information using reference motion information and the results of the motion capture. The motion estimation unit estimates a subsequent motion of the user using the user error information. The actuation unit controls the smart wear of the user in real time using the estimated subsequent motion and the user error information.

Apparatus and method for controlling smart wear

An apparatus and method for transmitting data using a human body. The apparatus includes a parallel bit stream generation unit, a frequency selective spreading unit, a matched filter unit, and a transmission filter unit. The parallel bit stream generation unit outputs a parallel bit stream for an input serial bit stream. The frequency selective spreading unit divides the parallel bit stream into a preset number of bit groups, generates a single code vector by combining orthogonal code vectors corresponding to the respective bit groups, and shifts the center frequency of a transmission signal by spreading the single code vector using a frequency shift code. The transmission filter unit meets a transmit mask for the transmission signal.

Apparatus and method for transmitting data using human body

There is provided a chair and multimedia player comprising a sound transmission apparatus performing human-body communications. The chair and multimedia player comprise at least one sound transmission apparatus, wherein the sound transmission apparatus is disposed in a surface of the chair and multimedia player to allow a user to hear a sound signal when the user is in contact with or adjacent to the surface, and the sound transmission apparatus generates a composite signal including a sound signal and a demodulation signal restoring only the sound signal from the composite signal and outputs the generated composite signal and demodulation signal into a human body in order to restore the sound signal within the vicinity of the ears of the user.

Chair and multimedia player comprising sound transmission apparatus performing human body communications

Provided are a human body communication apparatus for non-contact communications using a frequency-selective baseband and a human body communication method for non-contact communications in the same. The human body communication apparatus may be useful to perform stable communications between users by reducing interference induced from other communication apparatuses without affecting interference between the users since data are transmitted/received between communication apparatuses adjacent to a human body by spreading and despreading the data using only spreading codes of a limited frequency band (frequency-selective baseband) in which an inductive electromagnetic field formed by an antenna shows the most effective characteristics.

Human body communication apparatus for non-contact communications and human body communication method for non-contact communications in the same using frequency selective baseband

A human body communication system is provided. The human body communication system includes a transmitter and a receiver. The transmitter transmits a frame including a preamble, which is a Manchester-encoded pseudo noise (PN) code, to the human body. The receiver receives the frame from the human body, performs Manchester-decoding on the frame, performs cross-correlation on the decoding result and the PN code, and performs frame synchronization using the cross-correlation result. Accordingly, clock and data recovery performance is improved. Efficient frame synchronization with reduced computation amount can be provided.
